Well my 1st MB/MB is up and running on a China 2 stroke and everything I read is true!!
I've done a search but kinda wanted a more direct answer.
1. The 415 china drive chain is a POS at about 1/2 qt of fuel used.
Is the #41 chain a direct replacement??
2. I have the needle all the way down in the slide, I'm running 32 to 1 after 4 heat cycles at about 10 to 1. Still seems way to rich(wet plug-oil and fuel). I haven't run it hard yet and the temps outside are cool.
Should I still wait to lean it out??(did a lot of 2stroke dirtbikes in the past)
